As the seasons change, so do the needs of plants. What thrived in the warmth of summer might struggle in the whims of in-between weather or the chill of winter. And while our indoor dwellers don’t face the same elements, they’re still sensitive to the slightest shifts in light, temperature, and humidity. A few adjustments here and there can keep them thriving all year round!
Spring—Get the Ball Rolling
As plants stretch out their leaves, soaking up the warmth and preparing for a flourishing year ahead, help them with these simple steps.
- Resume feeding with water-soluble fertilizers specific to each plant type. For flowering plants, opt for fertilizers higher in phosphorus and potassium to encourage blooming. If you grow foliage plants, choose the products with higher nitrogen for active leaf growth. Follow the instructions and concentration indicated on the label, as overfertilizing can cause chemical burns.
- If your plant has outgrown its current pot, spring is the best time to repot. Go for a pot just 1–2 inches (2.5–5 cm) larger than the current one to support growth without overwhelming the roots. Drainage holes are a must to prevent water from sitting at the bottom.
- With the onset of warmer days, bugs get on stage, too. Check your leafy collection regularly and, when needed, treat it immediately with insecticidal soap to keep infestations at bay.
Summer—Watch and Protect
While the bright sun fuels lush leaves and vibrant flowers, it may feel like sunshine and rainbows. Yet, several chores still require your watchful eye.
- Water plants more often, but let the topsoil dry to avoid overwatering and root rot.
- To keep humidity levels up, mist leaves frequently or use a humidifier.
- During summer, your green pets can enjoy the fresh air outdoors, but pick shaded spots to prevent intense sunlight from burning the leaves. To protect delicate and tropical plants from the midday sun, use sheer curtains indoors and place them under trees or near shaded walls outdoors.
- Succulents thrive in bright light but won’t appreciate being moved around without warning. To make the transition smooth, increase exposure by 30–60 minutes daily.
- Keep your plants out of cold drafts, especially when the AC is on.
Fall—Prep for Dormancy
As gold and crimson hues replace green ones, your indoor plants will appreciate you listening to nature’s cues, too.
- As temperatures cool, reduce watering gradually, adding 1–3 days to the intervals between sessions.
- Bring outdoor plants inside before chilly nights set in your region.
- Stop fertilizing by mid to late fall, when plants are going dormant.
- With less daylight, move your plants closer to windows, or consider buying a grow light. Keep them on bright windowsills throughout winter.
- Clean the leaves regularly to help your plants get all the light they can. You can rinse humidity-loving plants in the shower or wipe their leaves with a damp sponge. As for cacti, succulents, and velvety-leaf plants, gently dust them off with a soft cloth or brush.
Winter—Rest and Maintain
With chill air and soft snowfall outside, plant care naturally slows down. Guard your green beauties through the season with these simple actions.
- Skip fertilizing if temperatures and light levels drop. Only fertilize if your plants don’t enter dormancy and need warmth and extra light from grow lamps.
- Prevent frostbite by protecting your plants from drafts or touching cold surfaces on windowsills. You can insulate the windowsill with wooden stands, layers of cardboard, paper, or special cloth.
- Many plants, especially cacti, succulents, and bulbs, need a winter rest. Water less often and keep temperatures between 50 and 59°F (10–15°C).
- Humidity drops with the heating on, so mist moisture-loving species regularly. Always keep your plants away from heat sources to prevent them from drying out.
Don’t forget to check specific requirements for your plants to keep them happy and healthy. A few mindful adjustments will bring you closer to a thriving indoor garden all year long.
